SPECIFICATION forming part of Letters Patent No. 609,064, dated August 16, 1898.

Application filed July 3l, 1897. Serial No. 646,620. (No model.)

T0 all whom zit may concern.'

Be it known that I, EFFINGER E.WHIPPLE, of Utica, in the county of Oneida and State of NewYork, have invented certain new and useful Improvements in Oultivators; and I do hereby declare that the followin gis a full,clear, and exact description of the inventiomwhich will enable others skilled in the a'rt to which it appertains to make andl use the same, reference being had to the accompanying draw-j ings, and to the letters and gures of reference lnarked thereon, which form part of this specification.

My invention relates to certain newand novel features of improvement in a ridingcultivator.

The invention has for its objecty a more complete control over pivoted-wheel cultiva-` torsand other features of novelty hereinafter more fully pointed out and claimed.

The invention is clearly illustrated in the drawings, which, with the reference letters tooth b in position between the frame-bars.l

Fig. 12 is a side view of a portion of the toothbar and tooth-shank, the broken lines indieating the parts removed. Fig. 13 is a perspective View of Fig.12 with the tooth removed. Fig. 11i is a side view of the toothbar and tooth-shank, one portion of the tooth'- fastening showing that the same is wider than the other section of the tooth-bar. Fig. 16 is a perspective View of Fig. 14 with the tooth removed, the short strip of `metal forming a part ofthe tooth-holder, showing its engaging surfaces on the main tooth-bar. p Fig. 15 is a rear view'of a section of each of the three toothbars and the cross-bar c, bolted to the inner 5o tooth-bard', extending above the other two adjacent bars, also showing the location of the U-bolt g for surrounding and engaging the tooth-bar 29 for holding the connecting-bar c in union therewith, and a represents a front View of the cross-bar c, taken from the right of the cross-bar, as shown-in Fig. 15, e representing the series of vertical holes for providving means for vertically adjusting the same.

By this arrangement the tooth-bars on each section `of the series of tooth-bars can be held in the' samelhorizontal plane, the cross-bar c being made vertically adjustable.

The purpose of my invention is to make an i Figs. 1,23, and 7. The front ends of the two sectionsare united at 2, Fig. 1, to which the neck-yoke 3 is fastened. The rear ends of the two sections of the tongue are secured to axle 4 at 5 5, Fig. 3. The wheels 6 6 are mounted between bifurcated forks 7 7,which are formed of half-round steel united at the top by shrink-band 8, Fig. 1, which forms a shoulder or bearing for the adjustable box 9 9, having an` internal recess which admits the upper end of the bifurcated forks,w'hich forks have a vertical rotary motion in the bearings for allowing the wheels and bifurcated forks v to be turned.

' I accomplish the turning of the bifurcated forkspand wheels by means of the arm 10, rigidly secured to the inside bifurcated fork 7, as shown in Figs. 9 and 10. On the inner end of the arm 10, Figs.` 9 and lO, I provide a ratchet-face 11 andadj ustable step 12, Figs. 9 and 10, carrying ratchet-face13, Figs. 9 and 10. The two ratchet-faces are held together by means of a tap-bolt. (Not shown.) By loosenin g the tap-bolt the step 12 can be adjusted up or down to accommodate riders'having different lengths oflegs, from the longest to the shortest. By pressing in either direction upon the adjustable step the travel` of the wheel can be shifted in either direction through the medium of the shifting-bar 14E,

IOO

This shifting-bar is free to move in the direction of its length in either' direction and is supported at its rear, to-- ward each end, by antifriction-rolls 15. (Best illustrated in Fig. 3.) I use three rods, designated as outside rod 16, inside rod 17, and center7 rod 18. These three rods are pivoted to the shifting-bar 14 at 19. (Best illustrated in Figs. 3 and 10.) The rear end of the inner rod 17 is secured at 20, Figs. 9 and 10, to the arm 10. The rear end of the outside rod 16 is secured at 21 to the end of the wheel-bearing, outside of the wheel, as best illustrated in Fig. 7. The center rod or connection 18 is connected at 22 at its rear to a projecting iiange to the front of the adjustable box 9. By this arrangement of the wheels and bifurcated fork with the adjustable step attached thereto, through the medium of connecting-rods 16, 17, and 18, ar-` ranged, as heretofore stated, on each side of the cultivator, theoperator can shift at will the travel of the wheels by crowding upon the adjustable step in either direction. The three braces or connecting-rods 16, 17, and 18, connecting at the same pivotal point on the shifting-bar, and the rods 16 and 17 describing a triangle as they pass backward to the rear, the rod 16 connecting to the end of the wheel-axle and the inner rod connecting to the arm carrying adjustable step form rigid supports, so that the wheels can be shifted without loss of power or motion, and thus get rid of the lash in operating this class of cultivators, which has heretofore been found very objectionable. By this arrangement the center connection 18 forms a swinging point of the shifting-bar, which prevents the wheels from ever being held on deadcenters.

Another feature of my invention consists in providing means for adjusting the relative location of the wheels in or out. This is accomplished by providing a series of holes, as illustrated at 23 23, Fig. 3, at each end of the shifting-bar, and by shifting the pivotal points of the front ends of rods 16, 17, and 18 in or out on the shifting-bar, together with means for shifting the adjustable box 9 on the axletrees, which is accomplished by clampingbolts 24 with nuts attached thereto. By loosening the nuts the adjustable boxes 9 can be adjusted in or out to correspond with the adjustment on the shifting-bar, so that by this arrangement the width of the cultivator gangs can be either contracted or expanded, so that the cultivator can be used in a narroweror in awider space. In accomplishing this, attention must be given to having the shifting-boxes 9 on the axletrees shifted to the same relative line on the axletree, as the front ends of rods 16, 17, and 18 are pivoted to the shifting-bar.

For widening or narrowing the cut of the tooth-bars to correspond with the in-and-out adjustment of the wheels I provide two rigid cross-bars 25 25. (Best illustrated in Figs. 3 and 7.) These bars fasten to the two secshown in Fig. 11,) which connects the dragbars 29 to iianges 27. By loosening bolts 26, Fig. 3, fianges 27 can be moved or adjusted on the cross-bars and thus shift the drag-bars in or out to widen or contract the space occupied by the tooth-bars, and when shifted to the desired position by bolts 26 can be tightened and the flanges held rigidly in any position to which they may be adjusted. For holding the shifting-bar in a fixed position I provide shifter 30, Figs. 7 and 8, which is pivoted at 31, Figs. 3 and 8, to the cross-bar. The handle carries on the under side of it a downward-projecting pin 32, Fig. 8, which engages with connecting-arm 33 at its rear end, which is rigidly secured at 34 to the shifting-bar 14, Fig. 8. Moving the shifter 30 either to the right or left moves the shiftin gbar in the same direction. By inserting a pin through opening 35 in the shifter, which pin will engage the openingsin the rod 36, Fig. 3, the shifting-bar may be held rigid and the tool. used as a rigid cultivator.

The tooth-bars are elevated by cables 37, connected to the tooth-bars at 38, Fig. 1, the cables passing over sheave-wheels 38, Fig. 1, operated by levers 39 with the ordinary mechanism, the cable passing over the sheavewheels, and the upper end is connected to spring 40, Fig. 7, and the lower end of Jthe spring is rigidly connected at 38 with the tooth-bars. By taking up the cable at the front end at 40 the required tension can be exerted on the spring to keep the tooth-bars at a uniform depth in the ground,'and bylocating the cable in proper position on the sheave-wheels and securing it rigidly thereto the depth of the working points of the teeth in the ground can always be regulated at the will of the operator. The mechanism for securing the cable to the shifting wheels is not shown, but reference is made to the patent heretofore referred to, of which this invention forms an improvement.

For adjusting the front end of the drag-bars up or down I provide a series of vertical holes in Iianges 27, which are best illustrated in Fig. 8. This is accomplished by removing the connecting-rod 28 and reinserting it to accommodate the up-and-down adjustment.

My improvement in the tooth-bars consists in forming crescent-shaped depressions 41. (Best shown in Figs. 12, 13, 14, and 16.) One of said crescent openings is formed in the regular tooth-bars 42 and the other is formed in a piece of metal which is bolted to the tooth-bar. I'Ieretofore the tooth-shank has been held by providing the crescent openings in two separate pieces of metal which have been bolted to IOO IOS

IIO

IIS

either side of thc drag-bar. By my arrangement one of the pieces of the metal is dispensed with and the regular tooth-bar is substituted in its place. By this arrangement half of the holding power of the tooth-shank is always a fixed and permanent part of the tooth-bar. I place between the two bars, at an angle deflected from vertical Vlines backward, the tooth-shank 43, which is round and may be adjusted in the direction of its length, or the tooth may be laterally adjusted by means of clamping bolts and nuts 44 by partially rotating the tooth-shank into any desired position and clamping the same by the bolts and nuts in the position to which it is adjusted. The tooth-shank 43 carries the working point 45. I g

For the hammock-seat to the lTying-cultivator I providea U-shaped metav ar 45,(best illustrated in Fig. 5,) with the front end deiiected upward and outward, as shown at 46, Figs. 4 and 5. In the deflected end I provide a series of holes 47 for adjusting the attach-` ing-points of the bar through the medium of boltf48, Fig. 4, which passes into or through each section of the tongue. I also provide a connecting-rod 49, Figs. 4 and 6, the upper end of which is hooked over the axletree, and the lower end carries the washer 50, extending under the U -shaped bar, and is made adjustable by the nut 51, by meansof which the pitch of the seat and the elevation of the rear portion of the U-s'hapedbar can be adjusted either up or down. At the rear portion of the U -shaped bar I provide an adjustable detachable seat 52, Fig. 4, which is bolted to the Washer 53 by means of clamping bolt and nut By loosening nut on the clamping-bolt 54 the seat can be shoved forward or backward, and by tightening the nut it can be held rigidly on the U -shaped bar.. By this arrangement the seat is supported on the U-shaped bar to the rear of the axletree and is made adj ustable forward or backward by the means already described and may be adjusted up and down by the means specifically pointed out.

Another feature of my invention consists in so arranging the tooth-bars that the cultivator can be used as a harrow, which consists in arranging the center tooth b (best shown in Figs. l and Il) so that this tooth and the connecting portions of the frame can be removed, so that the cultivator can be used on each side of a row of growing crops as a cultivator. By replacing the tooth the cultivator can be used as a harrow, with certain adjustable features which I will now proceed to more fully describe.

I arrange the two tooth-bars adjacent to the center, so that they can be elevated or de-- pressed by providing the two inner tooth-bars 29 29 (best illustrated in Fig. l) by removing the center tooth and the bars connected therewith at d in Figs. l and 1l. The cultivator can be used for cultivating a row of growing grain or crop, and when thus used it is frequently desirable to have the two inner tooth-bars or drag-bars 29 29 run deeper or more shallow, according," to the conditions of the crop and soil, than the outer tooth-bars with the teeth attached. It is frequently found very desirable to have the inner tooth-bars free to be adj usted in or out to accommodate the irregularities or crooks in the row ot' growing crops, and to accommodate these conditions I provide a tooth-bar coupling c, preferably made of steel, with an angle-bend d, provided with a series of holes e, vertically arranged, the holes being shown in dotted lines in the toothbar coupling. The angle-bend in the coupling is preferably bolted rigidly to the inner tooth or drag bars 29 29, and when thus fastened to the inner drag or tooth bars they can be adj usted up or down by shifting the attachingbolt through the proper hole, so that the two inner tooth or drag bars 29 29 can be freely swung in or out with the. foot` by inserting thetoe in loops ff, Fig. 11., and u when thus used the horizontal arms of the tooth-bar coupling c rides free on the top of the two adjacent drag or tooth bars.

For making the cultivator a harrow, by

having three independent sections I clamp the horizontal portion of the tooth-bar clamp c to the adjacent tooth-bar by a U -shaped bolt g, which surrounds the tooth-bar, and the tooth-bar coupling c permits the two bars to be connected adjustably in the position desired, and when adjusted to that po-` sition the same can be clamped together rigidly by the devices already shown, and in this way the three center teeth of the cultivator can be worked independent from the outer two sections of the harrow. When the center tooth and bars b, connected therewith, are in the position shown in Fig. 1l, forming a complete harrow, the center section being held by the U-shaped bolts in the manner heretofore described, the sections are free to work laterally as well as vertically.

Vhat I claim as new, and desire to secure by Letters Patent, is
